    Bug 673422 - Babl C type not accessible to introspection bindings
    
    https://bugzilla.gnome.org/show_bug.cgi?id=673422
    Annotate Babl C type to be Babl.Object in GIR using the
    "rename to" annotation in GI 1.33.5+. For earlier versions,
    use a static .gir file to achieve the same.
